That"s an impressive setup. I was most suprised that the KO Lee could handle so much weight being swung off the load bearing area of the bed. . I have a bit smaller tool cutter grinder but my radius attachment design is also much smaller. After seeing this I'm going to go ahead and finish it up. I really the spring loaded center idea. I'm going to add a provision for that on mine. You filled in many blanks for me. Great video.

Very informative and interesting on how some of these jigs work.

@brucegor here is our modified KO Lee and home made swinging device. Either between centers or in a 5C and one of our Accu-holds and we are able to swing radii within .0002" size and tangency.

I want ask you 2 things if you are able please make video for me Learn how change angles of HSS normal drill bit number 2 inch and grind it like hi performance carbide (with coolant flute) I mean i want Lean how grind it with 2 tip angle and narrowing phase of dtill for decreasing pushing force for penetrate to work pice, Secondly, i want ask you explain about your insert drill products, i don't know what type of products like gundrill you had been designed before this

Yeah nah, i still dont get how you center the axis of rotation with the wheel edge ??? For the radius formers from the IG pic

Impressive work. Can we grind 0.4 to 0.8 mm radius ?

Hi,i like your job,abd i only use your brand tools,,,,,

Did radius grinding all the time
